500 plus 800 equals 1,300.
780
800 + 29
If you mean:0 = 800 - 10x + 25 * 20 = 800-10x+25*210x = 800+50x = 8,50 = 800 - 10x + 25 * x * 20 = 800 - 10x + 50x-800 = 40x-50 = x
Oh, what a happy little question! To round 780 to the nearest hundred, we look at the digit in the tens place, which is 8. Since 8 is greater than or equal to 5, we round up to the next hundred, making it 800. Just a gentle little adjustment to bring a smile to your math journey!
